Among other things, corporations and alliances allow formal wars to be fought over resources, trade routes, strategic systems, customs offices, etc. Corporate wars allow the two warring corporations to attack each other with impunity, bypassing all security status penalties and CONCORD interference.

A war declaration (war dec) is a formal state of war between two player corporations or alliances. When corporations or alliances are at war the pilots belonging to them become legal targets for each other in all security levels of empire space. NPC corporations cannot be war decced by a player organisation.

Corporation or Alliance assets are also considered legal targets, i.e. Starbase Structures, Customs Offices, or anchorable containers.

You can see what wars your corporation is currently involved in, and check other corporations' wars on the wars tab of the corporation menu.

Declaring War

How do I declare war on a corporation or alliance?

To declare war on another corp you must have the director or CEO role in your current corporation, and then go to the 'Wars' tab in the corporation menu. Here you click on the 'Declare War' button at the bottom of the window. This will bring a new window where you can search for any player owned corp or alliance to declare war upon.

For an alliance, the process is different. The CEO or a director of the Executor Corp must open the Corporation interface, go to the Alliances tab, and then view the "Home" tab. At the bottom of the window is button labeled "Declare War." The CEO must push the button and enter the name of the target corporation or alliance, then press search. Once he or she has confirmed the selected alliance is the correct one, war is immediately declared, with fighting becoming possible after a 24 hour notice period.

How much does a wardec cost?

It costs 50 million isk, plus an additional cost for each member in the target corporation/alliance above 51. It will now start to increase with the 51st member and reach the ceiling of 500 million ISK at 2000 members.

The war declaration fee must be in the Master Wallet of the corp wallet.

I just started a war, what now?

After declaration, the war will go active 24 hours later. Wars will last 1 week unless either surrender is agreed upon, or if the war is extended by paying the fee for the next week of war. If the war bill is not paid, the war will end 24 hours after its due date.

Ending a War

Ending a war

To end a war, either the war bill must not be paid, or either corp must surrender (Directors and CEOs can offer surrender). When the war is ended a message will be sent to involved parties confirming the war invalidation. When a war between corporations has been ended it takes 24 hours for the war cancellation to take effect. During that time players can still shoot at each other without security status loss or Concord intervention.


Either corp can make a surrender offer to end the war. In the corporation menu, under the 'Wars' tab and the 'Our Wars' tab there under, click on the white flag icon to make a surrender offer. A new window will pop up where you can enter a message, and make an ISK offer.

If the offer is accepted by the other corp, the ISK will be transferred automatically between corp wallets, and the war will end in 24 hours thereafter. There is no war dec cool down period, so the same war may be declared again after the 24 hours.

Please note: A Corporation leaving an alliance at war will take with it all wars the alliance was in, with immediate effect. New wars will be declared with the leaving corp as aggressor if the alliance was the aggressor, and vice versa. The first week of war will be free. A bill will be issued for the second week of war, and if it is not paid, the war will end at the end of the free week.

Mutual Wars

A mutual war can be ended by either side surrendering to the other. Alternatively, the aggressor can retract the war if the defender has set the war to mutual.


Defending corporations in wars can enlist other corps to ally with them in the war. For more info, please refer to this dev blog:
